"Kpeng Exhaust"

So i was searching and came across this i dont have much money for an exhaust so this seems like a great option... Only problem is i have no idea what it is lol i hear people remove the resonators or something like that but from what this looks like it is as if they are just cutting off the muffler and adding some piping and some tips, is this correct and if so how much are shops charging to do this and im gonna assume i will be able to put the muffler back on in the future right? Lastly will I be able to pass NJ emissions test after the muffler is cut off? here is a link to what i found talking about kpengs exhaust but it doesnt talk about what he did from the start and yes i searched thats how i found this

do a search for "cherry bomb mike". he started the ghetto exhaust. resonators are basically small mufflers that run inline. in this case they are through flow cannisters that are packed with fiberglass to muffle the sound. "cherry bomb" is the brand of resonator.

here is one

cutting the muffler off and running pipes is great, it sound agressive and its not too loud at all, just slightly louder than stock. im getting my muffler gutted by a friend, when that goes back on hopefully this week, ill make a post about it. something like that will probably cost you around $150, of course if u know someone it will be much less.

Matter of opinion... some would say it's a bit obnoxious...

its really not that much louder, the only time it gets much louder is when youre hard on the gas. it mostly gives it a more aggressive growl

Not bad, I saw your vids a while ago. Sounds good. But did you remove your resonator/s?

Are you serious? Cutting your muffler and running pipes in its place is "slightly louder than stock"

You have to be joking... here is a clip of my car with that exact setup. To say it's "slightly louder" is comedic. I am not trying to be a jack@$$ but don't mislead somebody like that...




To the OP, if you want something slightly louder than what you have now and are looking to pinch pennies, order two "Glasspacks" and two exhaust tips online, take them to an exhaust shop, tell them to cut off your current exhaust, put the glasspacks in their place, and install tips on the end of it. Search for Kpeng exhaust (by title of thread) and you will find video's of ken's old exhaust setup. Do it that way and, should you decide you want more volume later, you can eliminate the glasspacks and just run piping in the exhaust's place.

i did this before, Basically you cut out the muffler and weld in Glasspacks and exhaust tips on the glass packs, it sounds nice in lower RPM but when you at WOT it sounds like its farting, like air blowing out with stuff in its way. It cost me about 190 dollars with Everything.

The glasspacks should be installed where the resonators are, not where the muffler was. That should improve the sound. I'm having the second resonator and muffler removed this weekend and having 2.25 pipes run from the first resonator back and a nice set of tips on the end. I'll post pics and vids as to how it sounds and how much it cost. A friend had this done and said he loves the sound.

If i may, you might want to remove the exhaust, drive around like that for a while, and then make a decision on removing a resonator. Far easier to chop more off later than it is to add on.

I say this as i have the muffler delete with both resonators in place and it's plenty loud.

Like i was hinting at above, that is with both resonators in place and only the muffler removed. Taking off the muffler and resonator(s) will be far LOUDER than most are anticipating.
